The synthesis of bacillamide A, a tryptamide alkaloid of marine origin, and its analogues from L-cysteine ethyl ester hydrochloride through an efficient and convergent synthetic approach is described in this work. The present two-step protocol involves the use of iodobenzene diacetate, a versatile oxidising agent, to synthesize the key intermediate ethyl 2-differently substituted-1,3-thiazole-4-carboxylates
在这项工作中描述了 bacillamide A、一种海洋来源的色氨酸生物碱及其类似物从 L-半胱氨酸乙酯盐酸盐通过有效和收敛的合成方法合成。本两步协议涉及使用碘苯二乙酸酯,一种多功能氧化剂,一步合成关键中间体 2-不同取代-1,3-噻唑-4-羧酸乙酯。在这项工作中,4,6二甲基嘧啶-2-醇作为酯的无溶剂氨解催化剂,利用其同时给予和接受氢键的特性获得了标题化合物。
